Hi all. Please help. Two days looking for solution on my problem cannot find. I have xoom mz602, first I thought that I have mz600. In the beginning tablet was working good also 3g EVDO internet of my local operator Intertelecom, I am from Ukraine. I know that there is some difference with regions for modem, maybe tablet from US but the connection on the adapter is UK. Internet worked good, but tablet itself worded very slowly. I decided to flash on stock firmware and then input setting for CDMA operator, I had conversation with technician and he gave me all I need. So first I flashed some firmware for 4G xoom which I found. I new that there are three xooms, just WiFi version, version with GSM 3G, version with CDMA 3G (MZ600) and upgraded MZ600 version with CDMA LTE 4G which is MZ602. When I press + and _ buttons togather with power I see "LTE modem off". So I understood that I have 4G version with LTE, but why it is off I didn't know. But I saw some man wrote that he also saw this in his tablet but modem works fine. Because of this "lte off" I understood that I have 4g LTE version. I tried almost all firmwares from MZ600 and MZ602 but I cannot same settings for modem, looks like modem has read only some parameters, and I do know know how to make them writable. I tried CDMA workshop, DFS, QPST. Maybe with some firmware I blocked the modem, and how to unlock it I didn't find. If someone know here on forum know what is my problem please help.
So, as I first time had problem with this xoom tablet, I din't know that LTE modem must be removed. As internet before was working I didn't know that I need to remove it. Looks like technician of internet provider company installed it back. This maybe help for someone. If you have MZ602 with LTE modem installed then just remove it and then you will be able to program your table with programs CDMA workshop, QPST, DFS etc.

hello all,
i've a 3g verizon us xoom. may i install uk 3g xoom's rom on it?
may i use a 2g/3g sim card after that?
thanks
Same Problem
Hi developers,
I have a very similar problem, except for I'm trying to use my US (used to be Verizon - but I UNLOCKED it) with China Unicom's 3G sim card. It won't pick up signal. I wonder if that is possible and what I need to change in order for it to work.
Any help will be appreciated,
thanks
The US xoom is cdma 3g and not gsm, which is why it wont pick up signal. Also the simcard slot is not for the 3g but for 4g which isn't available yet. I would doubt it would work.
Sent from my MZ604 using XDA Premium App
Verizons xoom is CDMA and the hardware is different, the sim slot in the verizon has no hardware yet. When the free hardware update comes in at some point it will be 4G not 3G.
So in short the answer is NO.
Lordao
YES! you can use any images on your verizon 3G XOOM!
I have tried several, and they ALL work!
you WILL get your SIM working as well!! but you will not be able to use the 3G GSM network, because the images do not contain the baseband files used for the radio.
Hardware differences have not been confirmed by anyone, people are just assuming. The radio chip used multi-frequency capable hence must be the same.
One must do a baseband firmware change, to find out if the CDMA to HSPA/GSM will work!
Check out this thread:

Ok
Thanks for your responses...
I'll go back to China Unicom and ask them for the CDMA 3G, since they're supposed to have that, too.
I just picked up an mz600 that's stuck in 3g land. Very proficient with adb and SDK and am used to being able to flash radios and what not with my cell phones.
On my xoom is there any way after I rooted and unlocked to be able to just fast boot the lte radio or flash the radio so I can sim card this thing and get lte?
I have searched and searched and haven't came across a real answer.
OK just found out my answer.
New question, does anyone know if a 4glte card from a mz602 is compatible with an mz600? I have found that I need the card first. Then install the lte card, then flash lte software, then I should be able to install a sim and have 4g.
OK. Here I am. I found out all my information. I have ordered the card and should have my 3g xoom on lte this weekend
We'll here is the update. I am pretty sure it would have been much easier than what I did but...
I have converted my 3g xoom to 4g lte
If you buy the lte modem and install it. Then unlock and flash rogue recovery and just flash the lte radios you will be able to use it.
The couldn't activate on their end because they kept asking for the meid because it was a 3g xoom on their network previously. I told them I did the conversion myself and when I got to tech support I found a fantastic tech. She was patient, got her manager involved. In the end we discovered she needed my imei number and not my meid.
Very happy.
But note you must use the imei after you upgrade. Or the sim will not attach.
i have problem with my data connection. when i set the preferred network to WCDMA only and LTE only. my phone has no signal at all. i have a strong 3G connection on my other phones.
is it a baseband problem?
if it is. how to flash the correct baseband for my F350L?
or this maybe a hardware problem?
thanks guys. appreciate who will help

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.

The 4G signal that the networks worldwide use are not the same, GSM 4G is not the same as CDMA 4G, also, some 4G devices in the past were not true 4G, they used Wimax which is not actual 4G. My point is, the 4G your network uses is probably a different signal type or its bands do not match the bands the device supports. Research the exact signal type and frequency bands that Verizon supports, then research what signal type and bands that your network supports.
Many times I've seen 4G CDMA devices used on other networks and 4G could never be made to work, they were stuck with 3G because the device did not support the 4G type their network uses.
Most devices on other networks but still have 4G can count themselves lucky.
Thanks for your reply,

You "think", no, don't assume anything, even if your provider uses 4G LTE, if the bands/frequencies of your network are not supported by the device's hardware then it isn't going to work. As I said the first time, you need to do the research to see what bands and frequencies Verizon uses and then do the research to see what bands/frequencies your service provider uses. I mean find the actual values of Verizon's bands/frequencies and the actual values of your networks bands/frequencies, you need to compare them to see if the use the same bands/frequencies, not just whether its 4G or LTE or not. Do you understand what I'm saying?
Also, their may be radio/modem incompatibilities, the radio modem is part of the stock firmware that remains on the device, ROMs are just the system partition and not the whole operating system, software that is under the ROM is still the software the device came with or had before you flashed a custom ROM.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.
so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios
